Gochapon are vending machines that dispense items in capsules. They are used heavily in Japan, and there are stores with banks of these machines.
In Father and son dissect a gachapon capsule toy machine to show us its magical insides【Video】/, a father and his son go to a gachapon store and see how they work.
They take one apart, and show that the mechanism is very simple. With a simple slider, one can set the price on the machine to 100, 200, 300, 400, or 500 yen.
